Abstract

ABSTRACTFactors that affect the shift in chemical equilibrium are materials that are still difficult for high school students, students experience misconceptions and have low understanding and motivation to learn. The demands of the 2013 curriculum should be student-centered learning and apply information and communication technology in the learning process. This research aims to develop integrated PowerPoint-iSpring learning media prompting questions on material factors influencing chemical equilibrium shifts of grade XI SMA/MA. The type of research used is development research using plomp model. PowerPoint-iSpring learning media is integrated with prompting questions. Questions are equipped with feedback on right or wrong answers so that students can be led in the learning process. The PowerPoint-iSpring learning medium also contains quiz questions and evaluation questions to be able to measure the extent to which students' understanding of the material factors influence chemical equilibrium shifts. Instumen analysis of data used in the form of validity questionnaires. The results of the assessment of each validity questionnaire assessed using Aikens'V obtained an average score of content validity, construct validity, and validity of media experts 0.091;0,907;0.933 with valid category. This research needs to be followed up in the form of practicality tests and effectiveness tests to know the practicality and effectiveness of developed media.Keywords: Factors Influencing Shifting Chemical Equilibrium, Learning Media Powerpoint-Ispring, Plomp, Question Prompting, Validity.ABSTRAKFaktor-faktor yang mempengaruhi pergeseran kesetimbangan kimia merupakan materi yang masih sulit bagi siswa SMA, siswa mengalami miskonsepsi dan mempunyai pemahaman dan motivasi belajar yang rendah.

Abstract

ABSTRACTInteractive learning media are able to make students active and increase learning independence so that they can support the demands of the 2013 curriculum in the learning process. The purpose of this study was to develop an integrated PowerPoint-iSpring learning media for prompting questions on hydrocarbon material. The Plomp model is the research model selected for development research, but the research stage is limited to the prototype III stage, that is expert review and one to one evaluation. The media assessment was assessed by five material expert validators who assessed the validation of media content and constructs, and three media expert validators who assessed media technicalities. The data collection instruments consisted of interview guide sheets, content validation questionnaires, constructs and media experts. The results of the assessment of each questionnaire were analyzed using the Aikens'V formula. The value of V on content, construct and media technical validation is 0.93 respectively; 0.93; 0.94 so that it can be concluded that the PowerPoint-iSpring learning media integrated prompting questions on hydrocarbon materials that have been developed is valid.Keywords:PowerPoint-iSpring, Prompting Question, Hydrocarbon, PlompABSTRAKMedia pembelajaran interaktif mampu membuat siswa aktif dan meningkatkan kemandirian belajar sehingga dapat mendukung tuntutan kurikulum 2013 pada proses pembelajaran.

Abstract

ABSTRACTThe Covid-19 pandemic has changed the face-to-face learning process to online learning. One of the subjects conducted online is chemistry. However, learning can take place well by utilizing various types of information technology (IT)-based platforms such as e-learning. Therefore, this literature review aims to discuss the implementation of chemistry learning during the pandemic, which includes the e-learning platform used, the response to chemistry learning and the challenges and obstacles faced during chemistry online learning. The research method used is literature study or library research. Meanwhile, the data sources used are secondary data obtained from various sources such as journals, activity reports, books and other sources relevant to the research. The research instrument is a check-list for the classification of research materials, writing maps and research note formats. The results showed that the most widely used learning platforms were WhatsApp, Google Classroom and Zoom Cloud Meetings. During learning, the responses of students were quite diverse, ranging from quite low to high enthusiasm. The obstacles of learning implementation in general are the internet network, lack of IT mastery, learning media that are less interactive. So that it is expected to be able to train IT mastery, especially how to use e-learning platforms and create interactive learning media.Keywords: Chemistry, Covid-19, E-Learning, Literature Review ABSTRAKPandemi Covid-19 telah mengubah proses pembelajaran tatap muka ke pembelajaran daring.

Abstract

ABSTRACT The availability of the chemistry game of snakes and ladders that have tested for validity, practicality and effectiveness, but has not tested for their effect on student achievement in the cognitive domain. The purpose this study to determine the effect of using the chemistry game of snakes and ladders on colloid material on students’ achievement of MAN 1 Padang Lawas. This type of research is a quasi- research and the research design is Randomized Control Group Posttest Only Design. The population of this study all students of class. Sampling used the Simple Random Sampling technique, so that the XI MIA 1 class was obtained as the experimental class and the XI MIA 3 class as the control class. From this assessment, the results of the posttest obtained with an average value of 82.2 for the experimental class and 78.8 for the control class. Data analysis was performed by t-test at a significance level of 0.05. The results of the analysis obtained tcount = 4.438 and ttable = 1.665. Because tcount > ttabel means H0 is rejected and H1 is accepted. It can be said that there is a significant effect of using colloid chemistry game media on the achievement in class XI MAN 1 Padang Lawas. keywords, influence, chemstry snake and ladders game, colloid, students’ achievement

Abstract

ABSTRACTScience learning which has lesson of concern makes students still not wholly able to develop their knowledge. This study aims to determine and explain the students level of science process skills using creative problem solving (CPS) models for students in practical activities and discussions. This research was conducted in the second semester of class XI IPA4 State Senior High School 1 Kampar in the 2018/2019 academic year. The selected material is solubility and solubility product (Ksp). Which designed by One Shoot Case Study without a comparison group using a sample of 34 students. The research instrument consisted of observation sheets, essay tests, and interviews used to determine the level of students' science process skills. Based on the data obtained, it shows that the highest aspect of students' science process skills is observing. Judging from the observation sheet on practicum activities, the average percentage is 77.82%. The lowest aspect of science process skills is the theoretical aspect which is only 61.29%. In comparison, the observation in discussion activities without practicum is also the highest aspect of observing with a percentage of 79 .99% and the lowest on the theoretical aspect of 69.98% and 88.88% based on post-test questions with good categories. Overall, the results of data analysis showed that the students' science process skills were good.Keywords: Science Process Skill, Creative Problem Solving (CPS), Solubility and its ProductABSTRAKPembelajaran sains yang memiliki pengajaran yang membuat siswa masih belum sepenuhnya bisa mengembangkan pengetahuannya.
